Cimetidine and ranitidine are H2 receptor agonists used to treat problems with this organ, while esomeprazole works by inactivating an H/K ATPase. Bombesin stimulates secretion by G-cells in this organ, which is missing in lampreys and hagfish. (*) Rennin in this organ serves to proteolytically inactivate kappa casein, forming curds, and was once harvested from young calves. Mechanical stress in this organ amplifies the signaling effect of cholecystokinin. Chief cells secrete pepsinogen while parietal cells serve to maintain an acidic pH. Helicobacter pylori commonly infects this organ and may lead to gastric ulcers. For 10 points, name this part of the digestive sys
